Chinese-built rockets are displayed at the 6th China International Aviation and Aerospace Exhibition in the southern Chinese city of Zhuhai Wednesday, Nov. 1, 2006. About 550 exhibitors from over 33 countries and regions with about 52 aircrafts attended the show.

CANNES,
France - A Chinese Long March 3B rocket on July 5 successfully orbited
ChinaSatcom's Chinasat 6B telecommunications satellite, the fourth satellite
built for Chinese satellite-fleet operators by Thales Alenia Space - the sole
Western satellite builder that has developed a product line designed to avoid
U.S. satellite component export restrictions.

Building satellites devoid of U.S. components
permits the spacecraft to be launched on a Chinese launch vehicle. Current U.S.
government policy effectively bars U.S. satellite components from being
exported to China.

Officials
from Thales Alenia Space, which is headquartered here, confirmed that Chinasat
6B was healthy in orbit following the launch from the Xichang Satellite Launch
Center in southwest China's Sichuan Province. The spacecraft, a Spacebus 4000
C2 satellite frame, weighed 9,920 pounds(4,500
kilograms) at launch and carries 38 C-band transponders. ChinaSatcom intends to
operate it from 115.5 degrees east longitude to provide up to 300 television
programs in China and elsewhere in East Asia.

Thales
Alenia Space has been cultivating the Chinese satellite market for more than 20
years. The company, under its former name Alcatel Alenia Space, built
components for the Chinasat 1 satellite before moving toward completed
products. The company is the prime contractor for the Sinosat 1, Apstar 6 and
Chinasat 9 satellites, in addition to Chinasat 6B.

Thales
Alenia Space officials say getting around U.S. State Department restrictions -
generally referred to as ITAR, or International Traffic in Arms Regulations -
with respect to China's rocket adds around six percent to the cost of a
telecommunications satellite. That is because these satellites cannot take
advantage of U.S. companies whose production lines are active and thus whose
unit costs are reduced - in addition to the fact companies producing in U.S.
dollars have an advantage over euro-based companies like Thales Alenia Space.

Officials
said that, as a general rule, the satellite price increase is more than offset
by the reduced cost of a Chinese rocket compared to European, Russian or
American commercial launch vehicles.

Even so,
they said they have no intention of moving toward what they refer to as a fully
"ITAR-free" product line. Such a move would help reduce the cost of
ITAR-free satellites by increasing the production volume, but would run the
risk of not being able to keep up with market demand because ITAR-free
satellites rely on a supply chain that would have difficulty increasing
throughput in the short term, Thales Alenia Space officials said.
